PosiTector SST salt tester (kun probe)

Introduction The PosiTector Soluble Salt Tester (SST) is a hand-held electronic instrument that measures the conductivity of a solution and calculates the concentration of water-soluble salts on metal surfaces in accordance with ISO 8502-6 (the Bresle Method) and ISO 8502-9. It consists of a PosiTector body (Standard or Advanced) and an interchangeable probe. The PosiTector SST is compatible with all Bresle Method-type patches including the Bresle Method DeFelsko PosiPatch, Bresle Method DeFelsko Patch and other adhesive patches. While compatible with any test patch, there are numerous advantages to the DeFelsko patch solutions. The Bresle Method DeFelsko Patch is low cost, latex-free, and works on nearly any surface geometry or material. It features a low-tack adhesive which creates a tight seal while remaining easy to remove without leaving behind any foam residue. The Bresle Method DeFelsko PosiPatch further simplifies the Bresle method. It requires no adhesive, as it is held to a steel surface by a magnetic holding ring. It has a built-in port which allows deionized (DI) water to be injected using a dull polypropylene dispensing tube, eliminating sharp needles from the test. It features a patented air-permeable membrane, which automatically releases trapped air as DI water is injected, then allows air bubbles to return and agitate the surface as solution is withdrawn. It is also reusable, and a single PosiPatch can be used for multiple tests. The PosiTector SST can be used as a conventional conductivity meter making it ideal for testing abrasive materials in accordance with ISO 11127-6 and ASTM D4940-15. See Bresle Mode.
